Hello I just have to write from the mobile phone, I started earlier when I saw after 4km city drive that the temperature control light lights red. Temp was in the red area. Engine at the traffic light immediately turned off, drove briefly again on and at nen parking lot. Thought the wp is broken but cooling water was normal much available, oil too. I left out the engine a little before I continued driving. After that the temp stopped at almost 90 degrees although the car could hardly be warm. J after 60km drive the temp in the city goes to over 90 degrees. Normal lay the otherwise at about 85. on the highway it lay at about 80 degrees at 140kmh. Someone an idea what is going on there? At home will put the diagnostic plug on it. Confused greetings
